Mark Webber using F1 break to go under knife

Mark Webber will undergo further surgery on the leg he broke last year after next week's Hungarian Grand Prix but will return for the following race in Spain.

The Red Bull driver, who is third in the title race after winning in Germany last week, needs to have screws removed from his right leg during the sport's traditional summer break.

There are four weeks between next week's Hungarian race and the European Grand Prix at Valencia on August 23, allowing the Australian time to recover.

"The titanium rod is coming out only after the season and then the bump on the lower leg will disappear," said Webber.

Webber admitted the injury, suffered when he was hit by a car while competing in his own charity challenge, had cost him early in the season after he spent most of the off-season off the leg.

"I think I was kidding myself a bit," Webber said. "It is absolutely clear that the leg was a long way from healed and it was still broken.

"It was just the metal holding it in place so it has come a long way since then."
